Built for stock to mildly modified street applications and heavy vehicles or trucks, this converter delivers a 2,200–2,800 RPM stall range for improved low-end torque and launch while maintaining efficient lock-up for highway cruising and reduced heat.\u003c\/p\u003e\n\u003cp\u003eThe Night Stalker series is engineered to handle up to approximately 500 horsepower. It features a thicker lock-up liner, modified stator, hardened chrome-moly impeller hub, oversized extreme-duty lock-up clutch, and Torrington-style encased bearings for greater durability than typical OEM or entry-level units. Fins are four-corner tack-welded (not just furnace-brazed) for long-term strength.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFits GM 4L80E \/ 4L85E transmissions with 2\" impeller hub (2-step input shaft)\u003c\/li\u003e\n\u003cli\u003eStall range: 2,200–2,800 RPM (application dependent)\u003c\/li\u003e\n\u003cli\u003eLock-up design\u003c\/li\u003e\n\u003cli\u003e35-spline input shaft\u003c\/li\u003e\n\u003cli\u003e11.675\" bolt circle\u003c\/li\u003e\n\u003cli\u003e1.703\" crank pilot\u003c\/li\u003e\n\u003cli\u003e~12\" diameter (factory core size)\u003c\/li\u003e\n\u003cli\u003eDigitally balanced and pressure\/leak tested\u003c\/li\u003e\n\u003cli\u003eHand-built in the USA (Muscle Shoals, AL)\u003c\/li\u003e\n\u003cli\u003eIdeal for mild performance street use, towing, and heavy vehicles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNotes: Actual stall speed varies with engine combination, vehicle weight, gearing, and tire size.
